T 0 all whom it may concern.

Be it known that 1, ROBERT E. SHARP, a citizen of the United States, residing at Esbon, in the county of Jewell and State of Kansas, have invented certain new and useful Improvements in Nonskid Mud and Snow Devices, of which the followingis a specification, reference being had therein to the accompanying drawings.

This invention relates to non-skid mud and snow devices, and has for its object the construction of a device that can easily be fastened over the tire of a motor vehicle, and which will prevent skidding or creeping upon an icy, or slippery, or muddy pavement or road.

With this and other objects in view, my

invention comprises certain novel combinations, constructions and arrai'igements of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a view, in side elevation, of a device constructed in accordance with the present invention, shown upon a rubber tire, while Figure 2 is a top plan view of the same.

Figure 3 is a section, taken on line 33, Fig. 1, and looking in the direction of the arrows.

Figure 1 is a perspective view of the auxiliary link of the central fastening device, while Figure 5 is aperspective view of the pr1- mary link of the same.

Figure 6 is a perspective view ofthe casing of the side fastening devices, while Figure 7 shows a blank of the same, prlor to folding. I

Figure 8 is an enlarged section, taken on line 88, Fig. 2, pnd looking in the direction of the arrows.

Figure 9 is an enlarged section, taken on line 9-9, Fig. 2, and looking in the direction of the arrows.

Referring to the drawings by mimerals, 1. designates the rubber tire upon which is placed my anti skid and slipping device. which comprises transverse chains 2, a central chain 3 and side chains 4:.

The transverse chains 2 comprise fiat links 5 connected by round links 6.

The central chain 3 includes the central,

round links 6, Fig. 2, and the flat, central links 7. i I

The side chains 4; include flat, side links 8 and oblong links 9; each link 8 comprises a narrow solid body with looped ends, in which ends the slidable links 9 are mounted. The length of the side chains 4 can be varied by turning the oblong links 9 to diflerent positions in the looped ends of the links 8; for instance, at A, Fig. 1, the oblong link is turned so that the side links 8 engage the corners of the link 9, giving a greater length to the side chain than if the side links 8 were engaging the long sides of the link, as the link is slightly oblong. hen the links 8 are engaging the ends of the oblong links 9, as shown in Fig. 1, with the exception of the link at A, the chains are of the greatest length.

The ends of the central chain are con- .nected by a central fastening device 10, Figs.

1, 2, 1 and 5. This central fastening device comprises a primary link 11 and an auxiliary link 12 (Figs. 1 and 5). The primary link comprises a flat body 13, which has, at its inner end, a shoulder 14, and integral with the inner end is an open hook 15. The body 13 is provided. with a plurality of vertical apertures 16. The auxiliary link 12 includes a flat body 17 in which are a plurality of parallel receiving and protecting grooves 18, and in' the body 17 registering with the grooves 18, are apertures 19, which apertures 19 are adapted to register with apertures 16, of the primary link 11. Integral with one end of the auxiliary link 12 is an open hook 20. The books 15 and 20, of the links of the central fastening device. receive round links 6 at the center or middle of the transverse chains, and these central, round links also constitute a part of the central chain 3. A bolt 21 is placed in the registering apertures 16 and 18 of the primary and auxiliary links 11 and 12, respectively, and a pin 22 is placed in the projecting upper end of the bolt 21, the pin and upper end of the bolt being in one of the transverse receiving and protecting grooves 18 of the auxiliary link, Figs. 1,

necessary to specifically describe one of the side fastening devices; said side fastening device comprises a sheet-metal casing 23, U-shaped in cross section, and this casing comprises a body 24 having a neck port-ion 25, and in the neck portion is a link-receiving notch :26. The neck portion 25 is provided with ears 2?, and in these ears are apertures 28. A pin 29 (Fig. 9) extends through the apertures 28 and through a hooked end. 30 of the end side link 8. The U-shaped body 2% straddles the central portion of the link 8, Figs. *2 and 6, and through the registering apertures 31, a pin is passed to prevent the body from moving of? link 8. Upon removing pin 32, the casing can be swung out away from the central portion of link 8 upon its pivot, constituted by pin 29, and then upon removal of pin 29, the oblong link 9 can be removed from the hook end 30 for disconnecting the ends of the side chains.

It is to be noted that I have produced a peculiar, central, fastening device, which is not efficiently adapted for fastening the side chains, for I have provided peculiarly-constructed, side, fastening devices for fastening the ends of the side chains together.

lVhile I have described the preferred embodiment of my invention, and have illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claim.

Vhat I claim is:

In device of the character described, the combination of chains, a fastening device connecting said chains, said fastening device consisting of a primary link and an auxiliary link, each link including an elongated thickened solid body, said auxiliary link being slidably mounted upon said primary link, said primary link having an aperture in its body, said auxiliary link having transversely extending grooves formed in the outer face of its body, said auxiliary link having apertures formed in its body and communicating with said grooves, a bolt fitting Within the aperture of said primary link and Within a selected aperture of said auxiliary link and extending into the groove communicating with the selected aperture of the auxiliary link, and retaining means engaging said bolt and fitting entirely Within the groove, as and for the purposes forth.

In testimony whereof I hereunto my signature.

ROBERT E. SHARP.
